Flat Panel/CRT Video Controller
The Little Board/486e CPU provides an integrated high-performance super VGA video controller
that supports both CRT and flat panel disp lay s. Ta ble 2 –27 pr ovid es a summ ary of the V ide o
Interface connectors and their specific use and features are described in the following sections.
It is possible to disable the on-board video controller by removing jumpers W11 and W12. This can
help developers recover from a misprogrammed video BIOS by allowing the installation of a second
display card. To re-enable the video controller, install W11 and W12 and reset the system.

Connecting a CRT (J5)

Analog video signals from the video controller appear on 10-pin dual row header, J5. These signals
are compatible with the standard video monitors commonly used with desktop PCs. Specifications
for compatible monitors are provided in Chapter 3.
Normally, signals from J5 are connected to a stand ard DB -15 v ideo co nne ctor by a tr ansi tion c able
made from a ribbon cable connector and a short length of 10-wire ribbon cable. The transition cable
can connect the video signals to a bulkhead-mounted DB-15 or DB-9 connector, allowing any
standard CRT to be easily connected using a stand ard moni tor v ideo ca ble. T able 2–28 g ive s the
signal pinout of J5 and pin connections for a DB-15 connector. Pin connections for a DB-9
connector, used for some monitors are also provided. Table 2–29 26 shows manufacturer’s part
numbers for mating connectors to J5.
